TIRE-UPS ETTIN G MACHINE.-

SPECIFICATIO forming part of Letters Patent No. ssroaa a r'ed April 10, 1888.

Application filed August 15, 1887.

To all whom it may concern.- I I Be it known that I, ROBERT BUTTER, of Butte City, in the county of Silver Bowand Territory of Montana, have invented a new and Improved TireUpsetter, of which the following is a fu1l,wclear, and exact description.

The invention relates to machines for upsetting or shrinking-tires; and the object of the invention is to improve the construction of machines of this character, the especial objects being to relieve the strain on the pinsthat connect the gripping-cams to the stationv ary and sliding heads and to allow a greater play-of the gripping-cams by having the operating-levers clear of the working parts.

The invention consists in the construction and combination of parts, as hereinafter described and claimed.

Reference is to be had to the'accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of a tire-upsetter embodying my improvements, one memberof the frame thereof being broken away. Fig. 2 is a section on the broken line ac'win Fig. 1. Figs. 3 and 4 are perspective viewsof the lever and link, respectively, for operating the sliding head.

The frame of the machine consists, preferably, of two parallel bars, a a, which are se-.

cured to a bench or table by means of the angleirons I), carried by'sai'd bars: In pract1ce there will preferably be four of these angle-irons, two at each side near the ends of bars a a. Astationar-yhead, c, is bolted in or between the bars a by means ofa bolt, d, which also holds two opposite angle-irons 'b to the said bars. The stationary headc is formed with aninclined, serrated, or corru gated seat, a, on its upper face and with an, upwardly-extending post or standard, a, from the inner face of which standard projects.

a boss, 0 .A toothed or corrugated cam, e, is formed with a recess, e, to receive the boss 0 and the pin f passes through the said cam and boss and through the standard 0, projecting beyond said standard to receive a lever, 9, by which the cam is operated to clamp the tire against {the seat 0 of stationary head 0. The boss 0 projecting into the cam e,forms a bushing for the pin f,and relieves the latter of much of the strain to which it would otherwise be subjected. A The sliding head h is formed with an inobtained practically indestructible;

z, and a] 1ever,j, for operating said cam, all

of the said parts being identical in construction and arrangement with those of the stationary-head c. I v

In a recess near the bottom'of the sliding head it issecureda link, It, by means ota pin or screw, Z, and the outer end of thelink is formed with an eye, lg,into which eye the eccentrically-bored head m" of. operating-lever m fits, and the said link and leveraresecured between the bars a a by means of a bolt or pin, a. With this construction, by throwingthe leverm the link In ismoved forward or backward, sliding the-movable head 71, to upset or release thetire, as desired. j

By forming the frame of the machine of the v two parallel bars a a a cheap construction I A By having thecamoperating levers g and j arranged on the outside of the'machine great I,

play is allowed, even to the extent of a full turn or rotation, and they can be operated withmoreconvenience andeffect than if they were arranged within thevertical plane of the other working parts.

Having thus fully 'describedmy invention, I

I claim as new and desire to secure by Letters 1 Patent- I I 1. The combination, in a tire-upsetter and with theheads or seats for the tire-formed with standards and with bosses projecting from I said standards, of gripping-cams recessed to re- I ceive the said bosses, substantially and described. 1 1 I I v 2; The separate parallel bars a, stationary and sliding headsch, gripping-cams*etf,and

as shown means, substantially as described, for operat ingsaid cams and sliding heads. I. 3. The combination, with the stationary heads oh and means for operating the latter, and the gripping-cams c1, of the pins f,- p'ro jecting on the outside of the machine,,an'd operating-levers gj, substantially as shown and described.

4. .The combination, with the machineframe,of the heads 0 h, formed with standards c h, and bosses projecting laterally fromsaid l 5 j, and the link and cam-lever k m, substanstandards, the gripping-cams e t, levers g r tially as shown. and described.
